The wiring harness is composed of wires with different specifications and performances. The main specifications and performance requirements are as follows:
●The cross-sectional area of ​​the wire
The cross-sectional area of ​​the wire should be selected according to the load and current of the electrical equipment. The general principle is that the electrical equipment with a long working time can choose 60% of the actual current, and the electrical equipment with a short working time can choose between 60% and 100% of the actual current. wires between.
● The color of the wire
The car’s circuit has a color and serial number on it. As automotive electrical equipment increases, so does the number of conductors. In order to facilitate the identification and maintenance of automobile electrical equipment, the low-voltage wires in the automobile circuit are usually composed of wires of different colors, and the colored letter codes are marked on the automobile PRZEWOD diagram.
In the circuit diagrams showing the car conductors generally marked as color codes (represented by one or two letters), the car colors of the wires are usually not the same, and the two principles of monochrome and color selection are commonly used. Such as: red (R), black (B), white (W), green (G), yellow (Y), black and white (BW), red and yellow (RY). Among them, the color line is the former, and the latter complements the color.
● Wrapping the harness
●Using semi-folding packaging, painting, drying and other processes to improve the strength and insulation performance of the cable.
● A new type of wiring harness, which is partially wrapped in plastic and placed in a side-cut plastic corrugated tube, making it stronger, more protected, and easier to find faulty lines.
